The STMicroelectronics LM2902WYDT is a quad general-purpose op-amp qualified to AEC-Q100, built for automotive and industrial environments where the supply rail can swing from 3 V to 30 V and the ambient temperature hits -40°C to 125°C. Each of the four channels delivers 40 mA output drive with a 1.3 MHz gain-bandwidth product and a 0.4 V/µs slew rate — enough bandwidth for filtering and scaling sensor signals like throttle position, pressure transducers, and current-shunt amplifiers in engine-control and chassis modules.
The 1.3 MHz gain-bandwidth product sets the usable closed-loop gain at a given frequency: at a gain of 10 the bandwidth is about 130 kHz, which comfortably handles PWM-filter and anti-aliasing stages in automotive sensor interfaces. The 0.4 V/µs slew rate limits the large-signal response — a 10 V step settles in roughly 25 µs. This is adequate for DC-level shifting and low-frequency signal conditioning but not for high-speed data acquisition or video buffers.
Supply span 3 V to 30 V — single-rail flexibility
The base product number LM2902 is a long-running industry-standard quad op-amp family; the WYDT suffix specifies the 14-SOIC package and the automotive-grade temperature range.
